Question

我似乎无法弄清楚这个PHP错误。我已经用“示例”替换了任何敏感信息，但我敢打赌这是我脸上的东西，我看不到它。

这是错误：

解析错误：语法错误，第272行/example.php中意外的文件结尾

<?php 
    session_start();
    // If you haven't entered a number, redirect back to index
    if (!$_SESSION['EXAMPLE'])
        die(header('Location: http://www.example.com/'));

    **//REMOVED THESE ON PURPOSE JUST FYI**
    $servername = "";
    $username = "";
    $password = "";
    $dbname = "";

    // Create Connection
    $con = new mysqli($servername, $username, $password, $dbname);

    // Check Connection
    if ($con->connect_error)
    {
        ("Connection failed: " . $con->connect_error);
    }

    // Search database for number
    $num = $_SESSION['exa'];
    $stmt = $con->prepare("SELECT * FROM numbers WHERE BINARY number = ?");
    $stmt->bind_param("s", $exa);

    $stmt->execute();
    /*$result = $stmt->get_result();
    $row = $result->fetch_assoc();*/

    // Get values out of response
    $example = $result['EXAMPLE'];
    $example = $result['EXAMPLE'];
    $example = $result['EXAMPLE'];
    $example = $result['EXAMPLE'];
    $example = $result['EXAMPLE'];
    $example = $result['EXAMPLE'];
    $example = $result['EXAMPLE'];
    $example = $result['EXAMPLE'];
    $example = $result['EXAMPLE'];
    $example = $result['EXAMPLE'];
    $example = $result['EXAMPLE'];
    $example = $result['EXAMPLE'];
    $example = $result['EXAMPLE'];
    $example = $result['EXAMPLE'];

    $con->close();
?>

Answer 1

<?php if ($_SESSION['EXAMPLE'] != NULL): ?>
<div class="portfolio-item">
    <span class="glyphicon glyphicon-user"></span><br />
    EXAMPLE
    <br />
</div>
<?php if ($_SESSION['EXAMPLE'] != NULL): ?>

您似乎缺少每个endif;（替代语法）结构的if ():语句。（这也会产生嵌套这些if构造的不良影响。）

解析器在if ():构造关闭之前到达文件末尾，因此＆＃34;意外结束文件＆＃34;错误。

例如：

<?php if (isset($_SESSION['EXAMPLE'])): ?>
<div class="portfolio-item">
    <span class="glyphicon glyphicon-user"></span><br />
    EXAMPLE
    <br />
</div>
<?php endif; ?>
<?php if (isset($_SESSION['EXAMPLE'])): ?>

我还将不等式比较（!= NULL）更改为isset()，这意味着同样的事情（已设置且不为空）并且可能更容易阅读。而且重要的是，如果未设置变量，则不会触发E_NOTICE。

这可能只是一个例子，但如果你真的一个接一个地进行相同的比较，那么你也可以将它们组合成一个if ():结构。

除了：

if (!$_SESSION['EXAMPLE'])
    die(header('Location: http://www.example.com/'));

如果未设置$_SESSION['EXAMPLE']，则会触发E_NOTICE。最好先检查!isset()或empty()，具体取决于它可能包含的值。例如：

if (empty($_SESSION['EXAMPLE']))
    // Error...

使用empty()更容易阅读，但请先检查这是否适合您的情况。变量被视为＆＃34;空＆＃34;如果它评估为 false （即＆＃34;＆＃34;，＆＃34; 0＆＃34;，0，false，null，未设置）。
